Martin Luther King Jr.'s speech calling for the US to end its intervention in Vietnam.

For historic clarity, I should point out some things King did not know. For instance, the NLF was run by secret Communists, the Viet Cong were mostly wiped out, and South Vietnam was ultimately conquered by the North Vietnamese Army.

But these details are not enough to invalidate King's main points. To preserve a US-friendly dictatorship against another dictatorship could not justify the violence that the US inflicted on Vietnam.

The details today are different but the US continues to inflict violence around the world — and poison its soul thereby.
